Widgets not nesting properly

Hi there Guru Phil
Something has happened and all my right sidebar blog widgets have moved to underneath my posts https://imgur.com/a/GbtHY1Q
In the page settings under the blog post I’ve selected main >> Layout >> Sidebar Right, but they’re not working https://imgur.com/w9Ggd2S
The same problem occurs on each individual blog page as well as on the blog masonry page.
Also, your blog masonry page at http://unicon.minti-themes.com/blog-2/blog-masonry/ looks nothing like my blog masonry page. How do I get mine to be small tiles like yours? Not sure how it became like this. This is what mine looks like https://imgur.com/DqOG26B. You can also see the missing widgets on the right side bar, because they are all down the bottom under the posts.
Please help.
Thanks.
